Add Volume-Based Coloring to TPO Letters (Darker = More Volume, Lighter = Less Volume)

Currently, in ATAS, each TPO period is assigned a fixed color based on time (e.g., Period A = red, Period B = another color). While this helps visualize time brackets, it would be extremely useful to allow an additional color mode where TPO letters change color depending on the volume traded at each price level.

This feature already exists in other platforms like Window Trader, where TPO letters get darker with higher volume (e.g., red or black for high volume) and lighter with lower volume (e.g., white or light grey). This allows traders to quickly spot high-volume areas inside each bracket without needing to overlay separate volume profiles.

It would be great if ATAS could include a setting to enable volume-based TPO letter coloring — either as an overlay or as an alternative to time-based colors.

This feature would benefit traders who rely heavily on order flow, volume analysis, and market structure, making the TPO chart more actionable at a glance.

Please consider adding this to future updates. I would really appreciate it, and I’m sure many other volume-based traders would too!
